Calcination is a solid-state synthesis process widely deployed in battery cathode manufacturing. However, its inherent complexity associated with elusive intermediates hinders the predictive of high-performance materials. Here, correlative situ X-ray absorption/scattering spectroscopy used to investigate calcination nickel-based cathodes, focusing specifically on archetypal LiNiO
